I V

' The method of propelling the vehicle is accomplished by utilizing the weight of the body on two, levers, one called thefoot lever, and the other called the saddle-lever. In'order that those skilled in" the art to which this invention appertains, may understand howto make and use the same, I will describe its construction in detail, referring by letters to the accompanying drawings forming a part of this application, in which:

Fig. 1, is aside view of, my present invention.

Fig. 2, is a top view of Fig. 1. F ig, 3, is a back view of Fig. 1, and Fig. 4, is a sectional elevation of the drum M.

. The saddle lever A isa long lever, one

end working freelyon a pin B fixed to the framework near the front end of the vehicle. To the other endof this lever is attached the saddle or seat C. Thepers'ons weightin the saddle or seat is capableof forcing it down a distance of about a foot, whereby this movement draws out a series of V powerful springs D having thcir respective ends connected to bracketsD and D The bracket D being supported'by the frame" member D and the bracket D depending from the saddle lever 1a'nd'8, g

WVorking in conjunction with the saddle lever is a lever for the feet. vThis said foot lever E worksv freely'on pins, F fixed to the framework at back end of vehicle, said foot lever E works below thesaddle lever A and extends inwards to the centre ofthe machine. To this end is fixed a footboard in such a position, thata person sittingjin the saddle or'seat G will be able to place his feet comfortably on it. The saddlev leverA. and the foot lever E are connected by a chain. H being secured thereto at'H and Htas' shewn inFig. 1, which runs over a roller J,

this roller being-suspended above the saddle 4 lever. If the saddle lever A'is forced. down by the persons weight, it automatically raises the'foot levertE. When the person raises himself from thesaddle A and stands on the foot lever E, by means of the chain attachment H aforementioned, the weight A as shewn in Figs 62,142, and invGreatBrit'ain October 20, .1924;

. of the-body upeg ine:

is a'driving shaftK, having a drum L ro-.

drum is -a small ratchet wheel M being Underneath the saddle lever tatably mounted, and encased in thissaid helpsito force .the I lever A 3' keyed tightly to the drivingshaft' K. In side said drum L are small ratchet pawls N, which engage inthe ratchet wheel when the drum L' is moved in. a forward direction as shewn in Fig. 4. The saddle leverA is connected to this said drum L by means of a chain O which latter winds round the drum L when the said saddle lever is forced down. Said chain 0 is wound round the drum L by means of another chain P to whichis attached a tension spring Q, whereby it will be readily seen that when a person raises himself from the saddle A and stands on the foot lever E the weight of the person is again brought to bear on this drum Lthereby operating the driving shaft K.
